The countries that grow the most illegal Opium are Pakistan, Burma, Thailand, and Afghanistan, which is also the worldâs top supplier of Opium. Opium can also be grown in places like Mexico and Columbia. Afghanistan accounts to over 90% of the worldâs grown Opium.
This equation, I = V / R, tells us that the current, I, flowing through a circuit is directly proportional to the voltage, V, and inversely proportional to the resistance, R. In other words, if we increase the voltage, then the current will increase.
An example of a series connection is shown in the diagram: For such a connection, the current is the same for all individual resistors and the total voltage is the sum. of the voltages across the individual resistors. Using Ohm's law ( ), one can show that, for a series connection, the equivalent resistance is. the sum of the individual resistances.
